Doing a thankless job is one thing. But doing a thankless job that benefits your sworn enemy is another.

In Syria, where the United States has contributed a total of $385 million in humanitarian aid, almost none of the Syrians receiving aid know it’s bankrolled by U.S. taxpayers, according to theWashington Post’s Liz Sly. Even worse, some Syrians believe the assistance is provided by the al-Nusra Front, the State Department-listed terrorist group that recently swore allegiance to al Qaeda leader Ayman al-Zawahiri. Here’s an example of one such Syrian:

“America has done nothing for us. Nothing at all,” said Mohammed Fouad Waisi, 50, spitting out the words for emphasis in his small Aleppo grocery store, which adjoins a bakery where he buys bread every day. The bakery is fully supplied with flour paid for by the United States. But Waisi credited Jabhat al-Nusra – a rebel group the United States has designated a terrorist organization because of its ties to al-Qaeda – with providing flour to the region, though he admitted he wasn’t sure where it comes from.

“If America considers itself a friend of Syria, it should start to do something,” he said.

All of this anger exists despite the fact that U.S.-purchased flour has fed 210,000 people per day and U.S.-purchased blankets have helped 168,000 people sleep. (It’s also worth mentioning that the United States is providing training and communications equipment to rebels and helping coordinate the flow of foreign weapons to opposition fighters.) According to Sly’s report, the United States can’t advertise its contributions because of security concerns.
